I am having the same issue so I am having my clients sign the Form 1040 in case it is not ready to go my March 2nd (Farmers) so I can take the returns to the post office to get postmarked on March 2nd.  ProSeries is having way way too many issues this year and I am about ready to go to Drake.  At least if it has problems, it is way cheaper so I will be paying less for having problems.  I have also found out that Form 172 is also not available.  Last year we had to prepare it outside of the program and attach it as a PDF which, although required some additional time, worked.  This year, if i attach it, the program will still not let me e-file the return.
